Patent DE-3122594-A1 (DE)
Title: Reversing device for a hydraulic turning apparatus of agricultural appliances
Inventor: VAN LAAK THEODOR ING GRAD
IPC: A01B3/421
Filed: 1981-06-06
Abstract: The invention relates to a reversing device for a hydraulic turning apparatus of agricultural appliances, especially of a turnover plough, for reversing the direction of movement of a double-acting piston/cylinder unit, especially in kinematically caused dead-centre positions of the turning apparatus, with a spring-loaded control piston (10) which is provided with two successively loadable operative surfaces, namely a first small operative surface (48) and a second large operative surface (49). For the universal use of such reversing devices in combination with inflow pressures of differing amount, it is generally necessary to adapt the reversal point by a suitable choice of inflow and flow-off throttles or the prestress of the return spring. Without adaptation, there is the risk of undesirable faulty connections in front of the top dead centre, especially when a reversing device designed for a low inflow pressure is used in the case of a substantially higher inflow pressure. These disadvantages are eliminated, according to the invention, by means of a third operative surface (50) directed counter to the other two operative surfaces (48, 49) and located on the control piston (10) or on a component connected operatively to the latter, for example an auxiliary piston (19) acting on the spring abutment (17), or on an auxiliary piston acting directly on the control piston (10), which operative surface (50) is loaded in front of a throttle point (23) incorporated in the inflow (13). As long as the flow takes place through the throttle point (23) until a kinematic dead-centre position or too high an external resistance is reached, the control piston (10) is held in its initial position in a reinforced manner, irrespective of the pressure level. When the flow ceases, the pressure difference across the throttle point (23) disappears and the control piston (10) can then be switched by means of any sufficiently high pressure at the first operative surface (48). In the second turning phase, the switching position is maintained in any event, since the second operative surface (49) is sufficiently large, even under comparatively low pressures, to overcome the restoring spring (16) or the force generated by the third operative surface (50). <IMAGE>
Patent DE-3123309-A1 (DE)
Title: Device for mounting an electronic component
Inventor: KRAHL BURGHARD ING GRAD
IPC: H05K7/20
Filed: 1981-06-12
Abstract: If an electronic component is mounted on a metal body by means of its cooling vane, it is generally necessary to insulate the cooling vane from the metal body. For this purpose, on the one hand an insulating disc is inserted between the cooling vane and the metal body and on the other hand the mounting means themselves are insulated from the cooling vane by means of an insulating bush. The insulating bush consists of a part (which is in the form of an annular disc) between the head of the mounting means and the cooling vane, and of a tubular part which insulates the shaft (shank) of the mounting means from the cooling vane. In order to ensure good electrical insulation and permanently good heat transfer, the insulating bush is manufactured from a material which is resistant to pressure and whose shape is also stable in the event of heating, and it has a bead on the edge of that part which is in the form of an annular disc.
Patent DE-3126224-A1 (DE)
Inventor: WIEDEMANN KURT
IPC: H03J7/18
Filed: 1981-07-03
Abstract: The signal-quality monitor has a filter (7) connected to the output of the FM demodulator (4). The filter has a relatively narrow bandwidth above the stereo-multiplexed signal inside the IF band. The filter's output is passed to an integrator whose own output is connected to the input of a level comparator (10). The comparator's output is coupled to a control (2) that tunes the receiver or performs other functions. The FM demodulator's output also passes via a bandpass filter (11) and a rectifier (12) to give a dc control signal that operates a switch (8) between the output of the first filter (7) and the rectifier (9) at the comparator's input. The switch acts as a gate and is only active when an LF signal is present. It opens when noise is excessive.

Patent DE-3210888-A1 (DE)
Title: Measuring arrangement for measuring flow velocities
Inventor: HAUBNER GEORG
IPC: G01F1/7084
Filed: 1982-03-25
Abstract: A measuring arrangement is proposed which serves to measure the flow rate and flow velocity of a liquid or gaseous medium in a line system, in particular to measure the fuel consumption of a motor vehicle. The measuring arrangement comprises at least two measuring systems (11, 12) of the same type which are arranged behind one another in a line section (10), the line cross-section in the region of one measuring system (11) being at least twice as large as in the region of the other measuring system (12). This change in cross-section produces different flow velocities at the individual measuring systems (11, 12) for the same flow rate, so that in the case of low flow rates the measuring system in the smaller line cross-section, and in the case of higher flow rates the measuring system in the larger line cross-section delivers the more exact measured value. It is possible by means of such a measuring arrangement for the measurement range to be subdivided into individual partial measurement ranges of high measurement accuracy or to be extended, as desired. <IMAGE>
Patent DE-3212436-A1 (DE)
Title: Transom block
Inventor: DETTMAR ULRICH
IPC: E06B3/96
Filed: 1982-04-02
Abstract: The invention relates to a transom block for fastening a hollow transom section especially for window frames. The transom block has a base which rests on and can be fastened to the frame spar and from which a locating part projects upwards. The hollow transom section or a hollow reinforcing section is pushed onto this locating part and subsequently fastened. An easy mounting and a use for the assembly of cross joints in windows are made possible in that the base is designed as a relatively wide foot which projects in the longitudinal direction of the frame spar above the pushed-on hollow sections of the transom. On these end regions of the foot which extend beyond the hollow sections, the transom block has fastening regions which are easily accessible for fastening means even after the transom block has been inserted into the frame spar and the hollow section of the transom itself has been pushed on.

Patent DE-3223215-A1 (DE)
Title: Method and device for testing transparent material webs
Inventor: HAUBOLD WOLFGANG
IPC: G01N21/896
Filed: 1982-06-22
Abstract: In the testing of flat glass for core bubbles (13), the radiation emerging laterally from the web (1) is detected and converted into electrical pulses. These pulses are compared with pulses which are obtained by the simultaneous scanning of a reference strip (21). The reference strip (21) consists of the same or a similar glass as the glass web to be tested and is provided with notches (24), arranged at an identical spacing, which lead to individual pulses. A core bubble (13) in the material web (1) to be tested in this case triggers a higher pulse than the notch (24), of the reference strip (21), located in the same area, so that the error can be unambiguously detected. The reference strip (21) can be provided with a sand-blasted light entry surface instead of the notches (24). It is also possible instead of this to arrange a mat adhesive strip below the reference strip (21). <IMAGE>

Title: Serial electronic adding/subtracting mechanism in decimal code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1982-07-24
Abstract: The subject-matter of the invention is a serial electronic adding/subtracting mechanism in decimal code, the two main parts (adding mechanism and subtracting mechanism) of which can also be used by themselves. The carry problem - increasing the relevant result number by the number 1 (in the case of addition) and decreasing the relevant result number by the number 1 (in the case of subtraction) - has been solved by arranging one shift circuit each which, in the case of the adding mechanism, forwards the H potential of the relevant result number to the next higher field when there is a carry present from the preceding addition and which, in the case of the subtracting mechanism, forwards the H potential of the relevant result number to the next lower field when a carry is present from the preceding subtraction. The two limit-case problems - addition carry with result number 9 or subtraction carry with result number 0 (zero) - has been solved by means of two additional circuits (5 and 6) which activate their carry memory on a standby path. <IMAGE>
Patent DE-3238020-A1 (DE)
Title: Device for conveying a liquid
Inventor: CONRAD RUEDIGER DR
IPC: F04B23/02
Filed: 1982-10-13
Abstract: The invention relates to a device for conveying a liquid by means of a pump. The use of geared pumps or diaphragm pumps for conveying liquids, particularly liquids with a high vapour pressure, is known in the art. Embodiments of these types of pumps suitable for transporting inflammable liquids are very expensive owing to the statutory safety requirements. In order to be able to convey a liquid cheaply, reliably and by simple means a device is proposed which is characterised by a further pump connected in parallel to the pump, a pressure regulating device post-connected to both pumps and a control unit detecting any fall in output of the pump and triggering a switch-over to the further pump.
